the clays of red zone, on which detached fragment- 

 ary masses of gypsum rest. The latter on the west side of the pass has 

 a thickness of 100 feet, dipping steadily to the east of south at 60°, 

 succeeded by the tertiary lower sandstones with a higher dip of 70°, in 

 the same direction and some traces of the red zone between. The lime- 

 stone comes from the north-eastward perfectly vertical, but just where it 

 ends is doubled partly back upon itself, increasing its apparent thickness 

 to nearly 100 feet, and in its general strike on the west side of the pass 

 a small mass of the limestone is crushed in among vertical tertiary 

 sandstones faulted against the Nurree (Nurri) gypsum. The vertical 

 and highly tilted bedding of the latter soon gives place to more moder- 

 ate dips as the beds pass gently beneath the Nurree (Nurri) synclinal. 



Northward of the Speena (Spina) gypsum tract the whole valley, 



Tertiary sandstone across to the Banda hills, is occupied by a perfect 

 basin of Sh*h Baz Ghur. quaquaversal basin in the tertiary sandstones lit- 

 tle less in size and more complete than the Nurree (Nurri) feature. In 

 the very centre of this a tabular mass of the sandstones edged by mural 

 precipices rises considerably above the neighbouring country forming 

 the picturesque site of the ruins of Shah Baz Ghur. Within this basin 

 the gray sandstones and red clays have the appearance of the middle 

 rocks of the series, and in the stream course beneath the hill on which 

 the ruins stand numbers of crystalline erratics from the upper conglo- 

 meratic beds of the series were found, whence it may be inferred that 

 these also once overspread this part of the country. 



An isolated and elevated trough of the lower tertiary sandstones, 



Tertiary sandstone nearly of the same size as the Speena (Spina) 



synclinal of Kurar. gypsum tract, occurs to the eastward, forming the 



upper portion of the mountain, summits of which are called Muzdukkai 



Sir and Kurar Sir.
